Classic Apple Pie

Classic apple pie is a double-crust pie filled with spiced apples and baked until the crust turns golden and the filling bubbles at the edges. The key is using tart apples that hold their shape and a crust made with cold butter, which creates those flaky layers everyone wants.

Ingredients for Classic Apple Pie

All-purpose flour forms the structure of both crusts. Butter, kept cold, creates the flaky texture. Salt and sugar in the dough add flavor and help brown the crust. Ice water brings the dough together without warming the butter. Granny Smith apples are tart and firm, holding their shape as they bake instead of turning to mush. Lemon juice brightens the filling and prevents the apples from browning. Granulated sugar and brown sugar sweeten the filling and help it thicken. Cinnamon, nutmeg, and allspice add warmth and depth. Cornstarch thickens the apple juices so the filling sets instead of running out when you cut a slice. Egg in the egg wash makes the crust shine and brown evenly.

Why This Classic Apple Pie Works

The crust depends on cold butter staying in separate pieces as you mix the dough. When the crust bakes, those cold butter pieces melt and create steam, which puffs the dough into layers. Warming the butter by accident, or mixing too much, breaks it into tiny pieces and you lose that flaky texture.

Tart apples like Granny Smith hold their shape during the long bake, while sweeter apples break down into sauce. The combination of granulated and brown sugar gives you sweetness plus a slight caramel flavor. Cornstarch thickens the apple juices as they heat, so the filling stays thick and doesn’t leak out onto your oven floor or soak the bottom crust.

Baking at 375°F (190°C) allows the crust to brown before the filling cooks through. Covering the edges with foil partway through keeps them from burning while the filling continues to set. The pie is done when you see thick, glossy filling bubbling at the edges, not when the crust looks done.

Mistakes To Avoid

Warm butter breaks into tiny pieces instead of staying in flakes, making the crust dense and tough instead of flaky and tender. This happens when you let the dough sit at room temperature too long, or when you work it too much with warm hands. The crust will bake up pale and crumbly.

Overmixing the dough after adding water overdevelops the gluten in the flour, making the crust chewy and hard instead of tender and crisp. Mix just until the dough comes together and you see no dry flour, then stop. If you keep mixing, the crust will shrink and toughen.

Cutting into the pie while it is still hot breaks the filling apart because the cornstarch has not finished setting. The filling will look like applesauce running onto the plate instead of neat slices. Wait at least 3 hours before cutting so the filling firms up.

Using sweet apples like Gala or Fuji turns the filling into apple sauce instead of apple slices. Granny Smith and other tart varieties hold their shape through the long bake and give you distinct apple pieces in every bite.

Ingredients

• 2 1/2 cups (312 grams) all-purpose flour
• 1 tablespoon granulated sugar
• 1 teaspoon salt
• 1 cup (227 grams) cold butter, cut into 1/2-inch cubes
• 6 to 8 tablespoons ice water
• 6 Granny Smith apples, peeled, cored, and sliced 1/4-inch thick
• 2 tablespoons lemon juice
• 1/2 cup granulated sugar
• 1/4 cup packed brown sugar
• 1 teaspoon ground cinnamon
• 1/4 teaspoon ground nutmeg
• 1/8 teaspoon ground allspice
• 2 tablespoons cornstarch
• 1 egg, beaten
• 1 tablespoon water
• 1 tablespoon coarse sugar, optional

Step-by-step Instructions

1. Mix 2 1/2 cups flour, 1 tablespoon sugar, and 1 teaspoon salt in a large bowl. Add 1 cup cold butter cubes and toss to coat with flour.
2. Using your fingertips, rub the butter into the flour until the mixture looks like coarse breadcrumbs with some pea-sized pieces still visible, about 3 to 4 minutes.
3. Sprinkle 6 tablespoons ice water over the mixture and stir gently with a fork until the dough just comes together, adding up to 2 more tablespoons water if needed. Do not overmix.
4. Divide the dough in half, shape each into a disk, wrap in plastic, and refrigerate for at least 30 minutes or up to 2 days.
5. Preheat the oven to 375°F (190°C). On a floured surface, roll one dough disk into a 12-inch circle about 1/8-inch thick. Transfer to a 9-inch pie pan, letting the edge hang over the rim.
6. Toss the sliced apples with 2 tablespoons lemon juice in a large bowl. In a small bowl, mix 1/2 cup sugar, 1/4 cup brown sugar, 1 teaspoon cinnamon, 1/4 teaspoon nutmeg, 1/8 teaspoon allspice, and 2 tablespoons cornstarch. Add to the apples and toss until evenly coated.
7. Spread the apple filling evenly into the crust. Roll the second dough disk into an 11-inch circle and place it over the filling. Trim the edges to 1 inch, fold under, and crimp with a fork or your fingers.
8. Mix 1 beaten egg with 1 tablespoon water. Brush the egg wash over the top crust and sprinkle with coarse sugar if using. Cut 4 slits in the top for steam to escape.
9. Bake for 25 minutes at 375°F (190°C), then cover the edges with foil to prevent burning. Bake for another 30 to 35 minutes until the crust is deep golden brown and thick, glossy filling bubbles at the edges.
10. Cool the pie on a wire rack for at least 3 hours before slicing so the filling sets and holds together.
